Another watching of the win over SUI reinforced how important the defensive effort was.
My totals for the second half:
18 "empty" possessions in which SUI didn't score
9 one-shot possessions, with defensive rebound
That success couldn't be sustained in the last 4 minutes when the fouls came thick and fast. SUI had 6 possessions in that stretch, and managed to shoot 11 free throws, while ISU only got two stops.
One or two more stops and one or two more buckets out of the offensive sets and ISU wins comfortably.
Its good to win, but the places for improvement are obvious.
